一种基于气动量仪检测平面度气密性的装置及检测方法
摘要：
本发明属于平面度检测技术领域，具体涉及一种基于气动量仪检测平面度气密性的装置及检测方法，包括气动量仪、内平面测试头、外平面测试头以及设有工作台的机架，所述气动量仪固定在机架上，所述内平面测试头和外平面测试头通过三通阀与气动量仪联通；内平面测试头和外平面测试头均设置在工作台上，内平面测试头外设有第一防护罩，外平面测试头外设有第二防护罩。通过上述结构可以有效减少占地设备的占地面积，并降低了设备成本。同时，在内平面测试头和外平面测试头外分别设有相应的防护罩，可以有效起到防护和防尘作用。
摘要（英）：

The invention belongs to the technical field of flatness detection and particularly relates to a device and method for detecting flatness air impermeability based on a pneumatic measuring instrument.The device comprises a pneumatic measuring instrument, an inner plane test head, an outer plane test head and a frame having a worktable, wherein the pneumatic measuring instrument is fixed to the frame; the inner plane test head and the outer plane test head are in communication with the pneumatic measuring instrument through a three-way valve; the inner plane test head and the outer plane test head are both disposed on the worktable; a first shield is disposed outside the inner plane test head; and a second shield is disposed outside the outer plane test head. The structure can reduce the floor space of land equipment and the cost of the equipment. In addition, corresponding protective covers are arranged outside the inner plane test head and the outer plane test head so as to have a protective and dustproof effect.
